Im a free member on this site and I saw images of exercises and some videos but is there a place where i can look up what some exercises are? I don't know the names of certain machines and such. For example, someone can ask me "What is a dumbbell row?" and I wouldn't know. I use primarily dumbbells and home exercises since I do not have access to a big gym and I need to change up what I do before I get bored.

I think she meant things like Lunges, Squats, Deadlifts, Cleans, etc etc, so she could match movements to names . I doubt most people would get confused about what things like dancing, jogging and swimming are.

They list out exercises by muscle group. All have their names with demonstration videos as well as listing individual muscles used in the exercises. You can use the site search as well to find an exercise you might just know the name of but not the muscles used.
